Esoteric K-03 analog outputs to bi-amps

Does anyone know if the Esoteric K-03 analog outputs (XLR and RCA) can both be active simultaneously with volume control?
I would like to hookup the K-03 directly to 2 amplifiers in a bi-amp configuration. Want to see if both analog outputs can be active.
In the manual it seems to say the analog out can be set to XLR, RCA or OFF.

You can only use 1 at a time. But even if you could, it wouldn't be good for biamping because the levels would be different.
